There many cheap oriental brothels which usually charge £100 p/h or £60 for h/r. Be prepared though for no OWO, only covered oral and no FK, just some lip kissing. Generally have a good attitude but no gfe experience. Plenty advertise on this website: http://www.hallo.co.uk/
although several also advertise on AW, vivastreet, backpage and gumtree.
I've been to a few in Wembley, but without FK & OWO, especially FK I haven't returned for a long time. I've had a post punt massage that was quite good from one which is a positive punting with an oriental girl.
